.To all-whomtrmyeeonmn:

' Be =it 1mownithat aIVJACoB IKLm'r, ,afcitizen ofithe 'United States, and lresident' ofithe borough of :Bxeoklymcounty o'f Kings,city and `State of New York, :have invented :eer-

- 'tain new andzuseful Improvements infBilge- Water Ejectors, o'fwhich the following is a specicat-ion.

This device is fintended ito perform a .multziplicityl ofduties, as a means'for supplying cooling Water 'to an engme,=as.a means 'for 'furnishing a muffled exhaust ffrom .the :engine, :as a .vacuum-creating means for use whereverand rfor whatever a Ivacuum may 4he useful, butiit is .principally intendedas a imeans 'for ejeeting tthe -bilge `Water 'from Ithelhold of a .vessel,by `a suction formeddoy the -passage vof the vessel through ithe Water, and is so1arrangedfthat it :is entirely auto- :matic in itsaction- It providesla freeand 'unobstructed 'liberal `passage outward 'for v'the'hilge Water, during such time asrthe boat is in motion, and having a positive v.means` \forautomatically fclosing the passage when the 'hoat is at rest or when traveling at a lspeed too-slow to maintain ausefulrsuction. The automatic'meansffor closing 'the passage, .although carefully designed may 'through some unforeseen reason,-\hecome useless, 1

have therefore -provided aimanually operated means 'for more or less'fperrnanently closing fthe-discharge passage if it is desirahle'to-do so. The connections .forrtheengine cooling means vare independent in operation, though 'the inlet is-connecteditotthe forwardend of fthe shoe, and the :outlet passes into the exhausted =part o'f the s'hoe -at' a pointfaft of the bilge Siphon valve. .It is desirable to :connectfthefengineexhaust to the'main shoe las in this Lway 'the exhaust 'from these-Xplosion isdischarged underwater and the suc- -tion Aon Sthe shoe relieves the engine from 'back pressure The followingzis what :Iconsider the-best meansof carrying out :this invention.

The accompanying drawings fform a part of lthisfspecieation, in `which:

At l, sIhave shown theEbottom-.of a vessel land Aalthough Imy device will 'work :equally well with .vesselsiofanytypa Ilhave shown a `vessel having a 'wooden hullzand an ordinary keel 2. y

rLlhe exterior member of the structure', which 1I haveaddedioathevessel, :is the shoe 3, construeted of sheetrs'teel or of anysother suitable material, :it is semi-cylindrical -in cross-sectiony and :is provided with an .interf nalbatlie @arranged mear-the forward end, which div1des=the `interior-of the -shoe into Both'ends o'f :which preventsithe inward `:passage `of foreign matter,suchas\weeds or piecesofdrift `wood,or even vishea'that `Would tend to clog vor make inoperativethe-several parts oflthe device. .The screens 5 are secured .into the lends'of the .shoe .insuoh afmanner that vthey -maylhefeas1ly removed when occasion may require.

'l fhave foundithat the: suction 'produced by 4a :smooth -shoe passing through the water, lalthough capable fof ;good work lis not suiiicient to withdraw the watemwiththe-proper degree of rapidity )nor `create the proper suction withinkthe shoe unlessthe boat Aloe Itraveling -at va ver-y great rate of speed, I have therefore designed 5certain improvements .that make the .shoe .much .more efflcientand capableof satisfactory operation even at -slow speeds. These limprovements consist in adding to theexteriorof the shoe a plurality :of .tins 6, which ,I Vhave shown. as arranged in y series, arranged along each side and-on1the-.bottom. Inadditon .to this .I have .added an outwardly 'extending flange '7, arranged about theopening in the `rearmost end of the shoe. llhepurpose of-these additions. is tofdisplace `agreater kamount of yWater rand thereby cause :a more ,powerful suction through the -shoe 3, :and .the parts attached thereto. The projections 6a .ar-

ranged about the forward end of the shoe perform the same general functions, whip ping-the water into numerous' small eddies 4and whirlpools and'causing a heavy drag or suction upon every outlet of the structure. I

l.A plurality of bolts 8, are the means by which the shoe 3 is secured to the hull, anda flange 9 is provided with a series o f holes 10 for the reception of the bolts 8. It is my intention that the upper face of this flange shall fit fairly Iagainst, the outside of the hull, though if the hull be'too rough, it mayy ^be advisable to calk`the seam between the flange and the hull.v An vup er plate 11, shown in Fig. 9 may beemp o ed to close the whole top of the shoe. Said shoe 3 is pro-4 vided with a perforation 12, and when the shoe is inposition the perforation 12 exactly registers with a hole 1 3, which has been produced in the bottom of the boat.

v' A screw threaded thimble 14 providedv with a ange 15', as asecuring means, is inserted into the hole 13, and projects upward into the hold of the boat for some distance. A locking ring or nut 16 secures the thimble reliably 1n position, and anysuitable/ packing 17 is placedy between the ring 16, and the' bottom sheathing of the boat. A guide member 18, which may be a circular spider having an -upwardly extending art 19, is placed upon the upper face o t e thimble `14, and a member 20, whichy is a. duplex valve member, and which may be a casting if such structure is preferred, is screwthreaded upon the th1mble.14 and forced downward until the shoulder 21 rests upon the member 18 holding it securely in position. The duplex member 20 is provided with two valve seats, one anangle seat'22 valve 23, and the other a fiat seat 24arranged tooperate with the horizontal disk valve 25. Both' of, these valves will bedescribed in detail. The passage through the duplex member 20 is a right angle-passage asis' shown in Fig. 1, and the height of the vertical portion maybe sufficient to carry the upper part close to the under side of passes through the central perforation of= the extension 19, and at its lower end receives'an'd retains the iioat'26, this ioat may be a copper c linder, or a cylinder of-.any other materia, but Ihave -constructed it ofa pluralit of cork disks held securely between the anges 27 and 28, and retained Vupon its stem by the nut 29.

When water, for any reason enters the shoe3, and attempts to ow upward through the thimble 14, it -lifts the float 26, and

closes the valve 23 againstthe valve-seat 22,l

screw operated disk valve, which may by turning the hand\wheel 31, be caused? to arranged to operate with the vertical floatthereb obstructing the passage. I have ar-A ran e -a spring 30 under the angle member f of e valve 23, to assist-the oat in urging the closure of this valve, thoughl it may-be found that this spring is `not necessary. If for any reason, the valve 23 does not `close and it is oundthat water is flowing inward through the shoe 3,' the passage may be closed by means of the valve 25, an ordinary positively and eliiciently' obstruct the sa e throu .h the duplex member 20.;

va ve 25, a though an ordinary disk valve, y

must be selected with a view to its peculiar duties, and becauseit is intended that it shall remain inoperativel for the greater part of the. time and yet be in condition for 'erfectf work` at a moments notice, it must conf structed of non-corrosive metals and have a valve-seat and disk thatwill not easily cut by the almost constant outow of water.

` A nipple 32,'which may be of any desired i i length is screw-threaded into jthe horizonr' tally arranged passa e` oroutlet ofthe du' 90 plex member 20, an connects therewith a cross fitting l33. This cross fitting is inserted to allow a number z of strainer membersAv to be connected to the system.. A second" i nipple 34, connects the strainer member shown in Fig. I to the system, as isv shown in Fig. 1. A.

The strainer member4 may morev properl be called the suction nozzle, as it is through this that the bilge water rstpa'sses. It is 100 a trum etshapedmember having a right-v angled end 35 at its upper end, and havingv a flange 36 formed about vthe flared lower end. The flange 36 is screw-threaded at 37 f v and receives the Strahler proper 3 8 upon the screw-threads. The strainer is rovided with a plurality of'lugs 39, by whic it may be secured tothe bottom, and whichplirmly support the strainer and the trumpet mem ber a certain predetermined distance above '1-10 the deck so as, to allow the water-to freely through the strainer 38; l

A member of my device-not. before described is the auxiliary cap 40,' shown in detail in Fig. 7. When it 1s desirable to re-A 115 move'this device for repairs or renewals, the f; boat being under headway will cause a suc*- tion through the shoe 3 and the thimble 14, the device may then be dis'ointed land the duplex member 2O unscrewe from the thim- 120 ble 14. The cap 40 is then screw-,threaded firmly down upon the thimble 14 and now, when the b'oat is stopped no'water can flow l into the boat'from the shoe 3. i

So far I havedescribed. but the bilge water 12 ejector but I will now detail the structure and operation ofv the'other parts.` The exhaust from the engine is connected to a nipple 41 which passes through .the bottom of the boat and terminates in an angled pas'- 13e susv ' sage 42. The open end of this passage is passage. When the boat is in operation and the shoe 3v has been exhausted, the pressure from the engine exhaust `passa e assists inv creating a suction for other useigul purposes.

I have before referred to a forward chamber arranged in the shoe 3, which is divided from the main .or larger passage, by the balie 4. A thimble 44 passlng upward through the bottom of the boat connects with this forward chamber and its upper end may be connected to the water circulating chambers of an engine .not shown. The outlet from the circulating chambers may be' connected with a thimble 45 which passes through thebottom of the boat and is let into t-he main shoe 3 at a point considerably aft of all of the other connections. The motion .of the boat through the lwater forces water upward through the thimble 44, through any parts connected therewith causing it to circulate about the cylinder of the engine if one be connected therewith to be discharged into the main shoe through the thifmble 45.

Modifications may be made within the scopeof the appended claim without departing from the principle or sacrificingy the advantages of this invention. Parts may be used without the whole.

At Fig. 7 I have shown a shoe of a soinewhat dlfferent construction that I have found to work well. l

Although I have shown'valves of a certain specified construction, it is obvious that any well operatin valves may be used. Having careful y and fully'described my invention, what I claim and desire to secure by Letters Patent is: A bilge water ejector having in comblnation with a suction nozzley and a valve member, a discharge shoe, said discharge shoe being provided with a plurality of fins, and an outwardly extending flange arranged upon its exterior for increasing the eiciency of said discharge shoe as herein specified.
